Summary: This project helped me expand my work station +2 monitors. The was an adjustment period having two additional monitors next to my smaller 17 Macbook Pro monitor, but that took no time. The only thing I wish were possible is to have an option for an external power supply. As others have noted, this unit requires an additional usb connection (the one closest to the power cord on your MBP laptop) to power it, thus sacrificing one usb port.
A hassle for the convenience of having 2 extra screens for my Macbook Pro.

Summary: The first Matrox DualHead2Go unit I received did not work very well. I could never get the unit to reliable connect to my computer, often times having to restart my computer multiple times for my computer to see the unit and send video feeds to my monitors. I contacted Matrox support and after a couple hours of letting them remote connect to my computer and mess with it themselves and saying they had never seen it do anything like this, they suggested I return it.
Summary: The DualHead2Go did exactly what it was supposed to do, it allowed me to connect my 2 Dell E207WFP monitors to my MacBookPro to create a massive 3 screen display. Setup was simple and it didn't even need the support software that came with the hardware. I tried the supplied software later and it was just a rehash of the mac's own configuration options.
Summary: Having recently converted from a Lenovo laptop with the optional port expander (that supported dual monitors in Windows) to a new Macbook Pro 15" non-retina model, it is unfortunate that one has to spend this much money in order to gain support for dual external monitors. Regardless, this device does work and for anyone that has ever used dual monitors you quickly realize what a huge productivity enhancer this capability offers.
Pros: Allows you to add 2 monitors to your laptop configuration instead of the default 1. Very small form factor. Comes with the necessary cables to hook up to your laptop.
Cons: The software disc that is included with the product is nothing more than an autorun file that links you to the downloads section of their website. The disc contains no software. If you try to install the software after downloading it from the website, the installation fails with a generic error. (Vista x64). Fortunately, the device works without their software. Also, the device does not come with a power adapter and you must use up a USB port to power the device. Ther...
Summary: If you're looking for a "plug and play" box that will easily connect your PC/Mac to external screens this item is NOT for you. On the other hand if you like experiments and are willing to spend a lot of time and patience then eventually you'll find a setting for which this box will work with your computer/displays. The product comes with no meaningful instructions and the tech desk cannot help much (though they are very nice and easily accessible).
Summary: I am using this product with my 2009 Macbook Pro 2.26 GHz 4 GB ram. I attached 2 samsung 24 inch monitor 1920x1200. The picture is great! setup was easy, just downloaded the required drivers following the instructions, then connected the monitors and selected the correct total screen resolution. The USB cable needs to be in the high power usb slot nearest the screen. I had one more monitor connected over USB, for 4 total displays (including the laptop display)!
Summary: I'm very happy with the Dualhead2go ME. It worked as advertised from the beginning and to my knowledge is one of the only ways to get dual monitors on a macbook pro (you can have a second monitor + MBP screen but that didn't work well for me). One time I did have the two screens flicker alternating one after the other but this resolved with a reboot and didn't recur.
